Radium Engineering 8AN ORB Direct Mount Regulator-Rotating Assembly (DMR-RA) – Black

The Radium Engineering 8AN ORB Direct Mount Regulator-Rotating Assembly (DMR-RA) – Black controls EFI fuel pressure and returns excess fuel so injectors see a stable, tunable pressure supply. Radium regulators are intended for performance return-style systems where consistent pressure control is important as fuel demand and manifold pressure change.

Radium specifies 8AN ORB AN/ORB sizing and Black finish options for this version, so confirm the surrounding system uses the same sizes and standards. A fuel return must be routed back to the tank or surge tank. Match regulator port sizes and pressure range to the fuel-system design.
